Borderlines will be set up for us not to be disappointed, 2018
According to the NYC Administrative Code, every owner, lessee or occupant of buildings is under an obligation to manage the sidewalks in front of them to the roadway. In case it was found that the sidewalk which is adjacent to his properties was not cleaned, he will be fined. When I thus had been observing the side walk, trash which was not removed came and went over the borderline as if it avoided the responsibility of that.
On a day on which the streets were heavily snowed, neighbors' attitude of the responsibility was clearly seen. I was skeptical at first, but then I was convinced. At that time, I left the invisible borderlines as a wall.
